(ithe ievers' 12 em" into moperative position 14 will be moved rearwardlyso as to swing the outer ends thereof forwardly thus moving the draw bar15 forwardl This bar is connected by a link 21 and pull rod 18 to theforward ends of two links 19 and 20, the rearward ends of which arepivoted to the inner ends of two levers" 22 and 23, respectively. Theselevers are pivotably mounted adjacent their rear axle b, are pivotallybrake beam 26 which carries at each end a brake block 27 movable intoengagement with the rear wheel 28 of the vehicle. When the draw bar 15is moved forwardly, the

and the outer ends of the levers levers 22 and 23 will be rocked abouttheir pivots so as to cause rearward movement of the brake beam 26, thusbringing the blocks 27 into operative engagement with the Wheels28 so asto exert a braking e liect thereon. The pressure which is exerted on theblocks 27 will vary directly with the rearward pressure exerted on theforward portion of the draw bar thus giving direct and automatic controlof the braking mechanism. When the end of the incline down which thevehicle is moving is reached, and the vehicle moves on level ground, orup hill, the forward section 4 of the tongue 9 will be moved forwardlyby means of the spring 5, thus returning the levers 12, 14 22 and 23 totheir initialposition and moving the brake blocks 27 out of engagementwith the wheels 28. t

hen it is desired to back the vehicle, it is necessary to provide somemeans for preventing application of the brakes. For this purpose, alatch or looking hook 29 is hingedly mounted on the casing 3 adjacentthe inner end thereof for movement about a pivot extending transverselyofv the casin This hook is adapted to engage into arecess 30 in the neck2 of the stub portion 1 of the pole. The two sections of the tongue willthen be locked against relative movement, thus permitting the tongue tobe used in the ordinary manner and preventing operation of the brakes.Normally, of course, the hook or latch member 29 will be turnedforwardly so asto permit the brakes to be operated in the 'mannerdescribed. v

In the form of the invention illustrated in Figs. 3 to 5 inclusive, thelevers 12', 14, 22 and 23, draw bar 15 and associated parts have beenreplaced by an operating cable 31 which is passed over grooved pulleys32 and 33 rotatably supportedin brackets 34 and 35 mounted on thevrearaxle b and tongue g respectively. The forward end of this cable issecured to a rectangularly disposed finger 36 provided at the innerrearward end of the bar 8 of casing 3 of the pole for tongue, therearwardend of the cable being secured through an eye-bolt 37 in thebrake outer ends, as at 24, on the connected by links 25 to a beam 26.In this form of the invention, as in the form illustrated in Figs. 1 and2, when the forward portion of the tongue or pole g is moved rearwardly,the brakes will be automatically applied to the rearwheels of thevehicle. Also, when the forward section is moved by the spring 5, thebrakes will be automatically released.

lVhile the invention is disclosed as applied to a vehicle adapted to bedrawn by draft animals, it will be obvious that it can beused equallywell with any vehicle which is drawn by suitable draft means, the tongueg being used for securing the vehicle to the means for drawing the same.The foregoing description and the drawings have reference to what may beconsidered the preferred or approved form of in- .vention. It is to beunderstood that I may make such changes in construction and arrangementand combination of parts, materials, dimensions, etc., as may proveexpedient and fall within the scope of the appended claims. I

' aving thus described my invention what 1 claim as new and desire tosecure by Letters Patent is 1. In combination with a vehicle includingfront and rear axles having supporting wheels, and a tongue including arearwardly projecting bar; of braking means including a pair of spacedlevers pivotally mounted .upon each axle, links connecting the innerends of the levers on the front axle to said bar, a draw bar havinglinks at its outer end connected to the outer ends of the levers on thefrontaxle, links pivotally connected to the inner ends of the levers onsaid rear axle, a link and pull rod connected to the last mentionedlinks and to said draw bar, 7 and a brake beam having links connectedadjacent the ends thereof to the outer ends of the links on the rearaxle, whereby as said tongue moves said first mentioned bar rearwardly,said links and levers, draw bar and pull rod will also be moved. so asto cause the brake beam to come into a binding en gagement with thewheels of the rear axle, .as and for the purposes set forth.

2. In combination with a vehicle running gear including a braking means,of a tongue consisting of a rear portion and a forward member,

said rear portion comprismg a stub having a reduced neck extendwherebythe hook may be swung into the reoess to hold said casing from shiftingalong said neck, thus said head may be swung over to fit upon saidcasing to permit of the casing moving upon the neck, and said tonguebeing connected to said runninggear, said stub having a keeper strapthereon, a bar extended from the rear end of said oasing and passingthrough said keeper strap Copies of this patent may be obtained forCHARLES W. SAMMONS.
